Issues while building PG in MS Windows, using MSYS2 and MinGW-w64

Hello,

I am trying to build PG from source, in MS Windows using MSYS2 and MinGW-w64. I've tried to build PG 10.0 as wells as 10.3.

I've done configuring like this

./configure --prefix="/d/pg10/"

And when I do "make" or "make world", I'm getting compilation error. I've attached complete error report at the end of the mail.

Basically, one error is pre-processor #error must have a working 64-bit integer datatype.

Another error is "redifinition of fseeko".

Another error is "FLEXIBLE_ARRAY_MEMBER" is undefined.

I don't know why the error is coming, I tried reinstalling MSYS2 and but still no luck. Could you please help?

My $PATH var is
